APPARATUS FOR CONVERTING PETROLEUM, &c., INTO GAS AND BURNING THE SAME.

SPECIFICATION forming part of Letters Patent No. 476,554, dated June 7,1892.

Application filed septemher 30, 1891. Serial No. 401319. (No model.)

To all whom it may concern:

Be it known that I, GEORGE F. RANDOLPH, a citizen of the United States,and a resident of Little Genesee, in the county of Allegany and State ofNew York, have invented certain new and useful Improvements in Apparatusfor Converting Petroleum, its Products or Residue, into Gas and Burningthe Same; and I do declare the following to be a full, clear, andexactdescription of the invention, such as will enable others skilled inthe art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, and to the letters of reference markedthereon, which form a part of this specification.

Figure 1 of the drawings is an end view showing the invention as appliedto a boiler. Fig. 2 is a perspective view of the invention, and Fig. 3is a sectional detail view.

This invention relates to apparatus for the conversion ofcrude-petroleum oils or any of their products of distillation or residueinto gas; and it consists in the provision of suitable means for thispurpose especially calculated to render the device capable for use inlliGbOXGS of steam boilers or generators for furnishing the necessaryheat.

In the accompanying drawings, the letterA designates a suitablereservoir located outside the generator 13 and into which is placed theoil or hydrocarbon to be converted. Communicating with this reservoir ata is a feed pipe C, the opposite end of which discharges into a pipe E,one end E of which connects with the steam-dome of the boiler and at theopposite end connected and communicating with the primaryconversion-cylinder D.

Inside of the pipe E is a jet-piped, terminating at a point just outsidethe conversioneylinder. The action of the steam in this pipe serves todraw in oil from the reservoir A and highly-heated air through a pipecoinmunicating at one end with the pipe C, its free end terminating in aposit-ion to receive the heat of the burner. The inner portion of thepipe E around the jet-pipe serves as a mixing-chamber for the hot airand oil, which are subjected to the action of and mixed with the steamat the discharge of the jet-pipe at the point d. Said jet-pipe takes itssteam from the pipe E and enters the pipe E at the point a through aplug or diaphragm in such a manner as to exclude the entrance of anysteam around it. This hot air, steam, and oil forced into the cylinder Dare partially converted to vapor therein, passing thence through a pipeconnecting G to a second cylinder D, where full conversion takes place,the vapor being discharged through the pipe II at the burner h in ahighly-heated and inflammable condition. The cylinders D D. are ofsuitable material calculated to withstand great heat, and are supportedby suitable means on the fire-box K of a boiler or generator, as shown.Suitable regulators, cocks, and valves are provided for the variouspipes.

Having described this invention, what I claim, and desire to secure byLetters Patent, 1s-

1. The apparatus for the purpose herein described, comprising theoil-reservoir A, feedpipe 0, discharging at its lower end into asteam-supply pipe E, the primary retort or cylinder D, into which saidpipe E leads, a jet-pipe d within said pipe E and terminat ing justoutside the retort D, the secondary retort or cylinder D, connected withthe cylinder D, the discharge-pipe l'I, terminating in a burner, thel1ot-air supply-pipe lying in proximity to said burner at one end and atthe opposite end communicating with the pipe 0 above its point ofdischarge, and the regulating cocks or valves in the several pipes,substantially as specified.

2. The combination, with the fire-box of a steam boiler or generator, ofthe retorts or cylinders D D, arranged side by side therein andconnected one with the other, a steamsupply pipe leading from the domeof the boiler to the primary cylinder D and forming a mixing-chamber, ajet-pipe in said steampipe and terminating at one end just outside saidcylinder, an oil-supply pipe discharging into the pipe E around saidjet-pipe, a hot air pipe, one-end of which is in proximity to theburner, communicating with the oil-supply pipe above the point ofdischarge, and the necessary regulating cocks or valves, substantiallyas specified.

In testimony whereof I aflix my signature in presence of two witnesses.

GEORGE F. RANDOLPH.
